Short-term, seasonal and annual variation characteristics of unusual tides are analyzed using over 30years' sea level data both for southern Kyushu region and Nansei islands region. Effects of atmospheric pressure on the unusual tides are also discussed. The greatest contribution to the unusual tides comes from the atmospheric effects. However, for the short term variation of the unusual tides, longer term fluctuations more than 40days which are considered to be irrelevant to typhoon directly induced motion become dominant for Nansei island region. The sea level fluctuations at Nakanoshima site are found to be closely related to the variations of Kuroshio axis in the Tokara strait.
